We have studied the behavior of the superconducting critical temperature Tcin $Nb/Co_{60}Fe_{40}$, Nb/Ni, and $Nb/Cu_{40}Ni_{60}$ bilayers as a functionof the thickness of each ferromagnetic metal layer. The Tc s of three sets ofbilayers exhibit non-monotonic behavior as a function of each ferromagneticmetal thickness. Employing the quantitative analysis based on Usadel formalismof the effect of the exchange energy, we observed that the Tc behavior of$Nb/Co_{60}Fe_{40}$ bilayers is in good agreement with the theoretical valuesover the entire range of the data. On the other hand, the Tc s of Nb/Ni and$Nb/Cu_{40}Ni_{60}$ bilayers show a higher value in the small thickness regimethan the theoretical prediction obtained from the calculation, which matchesthe dip position and the saturation value of Tc in the large thickness limit.This discrepancy is probably due to the weakened magnetic properties of Ni and$Cu_{40}Ni_{60}$ when they are thin. We discuss the values of our fittingparameters and its implication on the validity of the current Usadel formalismof the effect of the exchange energy.Comment: 10 pages, 5 figures and 1 tabl
